This invention relates to apparatus for* shearing flanges from ingots.

In the copending application of L. Gerald Firth for ingot molds, Serial No. 385,255, filed August 12, 1929, there is disclosed a` method of forming ingots having flanges thereon. The ingots are cast in ingot molds provided with recesses which form flanges" on the ingot. formed, the flanges are separated from the body of the ingots which contains the shrinks,t pipes and segregations and the flanges are: rolled or otherwise shaped to the desired form.

The present invention provides an apparatus for shearing the flanges from the body of the ingot.

In the drawings, which illustrate the present preferred embodiment of our invention,

Figure 1 is a partial vertical section showing a supporting die for an` ingot having four flanges; and

Figure 2 is a similar View of the apparatus used for severing the flanges from an ingot having three flanges.

Referring more particularly to the drawings, there is shown a lower die 2, mounted on a base 8, and a pressing head 4 secured to a recip-rocable plunger 5. The die 2 is provided with pockets 6 which receive the flanges 7 of the ingot A. The pockets 6 are larger than the ingot flanges 7 so as to provide clearance 8. In order to take care of any slight inequalities in the size of the flanges. The ingot is secured in the die 2 by a wedge l0 which is slidable relative to the die. The wedge is tapered and is moved relative to the die by a toggle lever not shown. When in the position illustrated in the drawings, the wedge contacts with one of the flanges 7 to rigidly hold the ingot in the d1e. The wedge 10 is provided with a dove-tailed portion 11 which slides in a corresponding groove in the die. The wedge is also provided with a flange 12 which contacts with one of the flanges 7 and prevents the ingot from turning during the severing operation.

The pressing head 4 has a knife 13 secured thereto by means of a bolt 14 and nut 15. A clearance pocket 16 is provided in the die to Application med August 20,1192@ serian 110.387,135.

After the ingots have been lreceive'the end of the knife. This clearance *pocket 16 is formed in the surface 17, which -f supports Vthe flange 7 which kis being severed. In the operation of severing the flanges-, ',fr'om the ingot, the pressing head 4 and knife 13 are moved'toward'the ingot to force'the :knife'entirely through the flange and to completely-sever it from the body of the ingot.

OE .MCKEESPORE PENN SYLVA-ii h The ingot is thenrotated so that another.r`

flange 7 rests on 'the supporting surface 17" and the pressing heady is again lowered to shear *off the second? flange. This operation 1s, repeated -until all of the flanges are rebetween the ingot and the wedge 10.

ingot B has three flanges 7a. Corresponding 'parts in'this ligure are indicated by the sameAk reference numerals with the letter a sulixed thereto. In the embodiment shown in Fi ure 2, the wedge 10a is vof such shape that'it holds the ingot B frombeing displaced from the die 2a. It is not necessary to provide the wedge 10a with a flange such as the flange" l2 shown in Figure 1. The operation of sevmoved? AWhen severing the last flange it ism ynecessary tol insert a'lli'ng'rpiece, not shown,"

ering the flanges is the same as described Vin f connection with'the embodiment shown in Figure 1.

We have illustrated and described the apparatus used for severing the flanges from ingots having three and four flanges. The invention is applicable irrespective of the number of flanges on the ingot. In the pre-H ferred forms of the apparatus illustrated in vthe drawings, the pressing head reciprocates in a vertical direction. If desired, however, the pressing head maymove in a horizont-a1 direction, as is common in the bull-dozer type apparatus. The pressing head may be of the pressing type or the hammer type.

Other changes may be made in the apparatus without departing from the s irit of the invent-ion or the scope of the fo lowing v claims:
